“Aggressive Underdog vs. Cool Counterpuncher,” Washington Post

“McCain Brings Heat, Obama Stays Mr. Cool,” Chicago Sun-Times

“Debate Sees An Aggressive McCain and a Cool Obama,” The Hill

“A fiesty McCain, a cool Obama, and appeals to ‘Joes’ everywhere,” Christian Science Monitor

“McCain seemed energized; Obama kept cool,” Denver Post

“Cool” or “too cool”?
